Relativistic Causality: Lorentz Transformation in Special Relativity

The assertion about the possibility of motion faster than light does not contradict the special relativity. In order to develop the special relativity, is sufficient to assume independence of the speed of light on the reference frame. From equations of special relativity, it follows that object moving faster than light in vacuum cannot be carrier of causal relationship.In the reference frame S3, moving with superluminal speed relative to the reference frame S2, temporal and spatial axes are swapped. Therefore, causal relationships in reference frames S2 and S3 are different. There exists a reference frame S1, moving relative to the reference frame S2 with speed v
